The system of linear equations x + y + z = 6, x + 2y + 3z = 10, x + 2y + 2z = 4 will have
non trivial solution
Once you express the given equations in the form of matrices then the determinant D = −1, D1 = −8, D2 = 8, D3 = −6. Here D ! = 0, none of D1, D2, D3 are zeros. So according to Cramer's rule there exists non trivial solutions and the solutions being x = D1D, y = D2D, z = D3D
